基于逐流高频反馈技术的电子节能灯

Electronic Energy-saving Lamp Based on the Valley Fill and the High-frequency Feedback Technology

普通电子节能灯通常采用不可控整流,使得输入电流严重畸变,谐波含量多,功率因素低。针对这一现象,利用逐流高频反馈技术设计了电子节能灯。结果表明,电子节能灯中应用逐流高频反馈技术,提高了节能灯输入功率因素,降低了输入电流总谐波畸变,是一种高性价比的电子节能灯设计方案。

The ordinary electronic energy-saving lamp usually uses uncontrollable rectifier. The input line currents have significant distortion, high harmonic content and low power factor. In response to this phenomenon, the electronic energy-saving lamp is designed by using the valley fill and the high-frequency feedback technology. The results show that the input power factor of energy-saving lamp is improved and the total harmonic distortion of input current is suppressed by using this technology. It is a cost-effective design of electronic energy-saving lamps.
